 +**Seminar:** Chipless RFID: Revolution in Identification in the New Millennium
 +**Speaker: A/Prof Nemai Karmakar**
 +
 +**Abstract:** Radio Frequency IDentifcation (RFID) is one of the fastest growing technologies in recent decades. RFID is an omnipotent identification technology that has many significant applications. As for an example, car immobilizers use RFID technology. However, the penetration of RFID in low cost item level tagging is hindered due to its high cost. The application specific integrated circuit (ASIC) micro-chip in the RFID tag is the most expensive item in a tag. Researchers have been working to remove the chip from the tag so that the tag can be made fully printable and low-cost. However, printing microwave circuits on low grade packaging and labelling materials is not a trivial task. Tremendous design flexibility and high precision printing with high conductivity ink are needed to design microwave circuits on these materials. Additionally to these stringent requirements, reading of this tag is tremendous challenging due to its low fidelity response. No conventional protocols can be added in the chipless RFID tag as they have no on-board signal processing capability. Therefore, a fully new development of chipless RFID reader is needed. This seminar will present chipless RFID tag and reader for low cost item level tagging.

 +**Seminar:** Terahertz quantum cascade lasers: physics and challenges in design, growth and fabrication
 +
 +**Speaker: A/Prof Dragan Indjin**
 +
 +**Abstract:** Terahertz quantum-cascade lasers (THz QCLs), first realised in 2002, have now
 +reached technological maturity. However, with maximum operating temperatures
 +around 200K in pulsed mode, and ~ 250K in the strong magnetic field, a number of
 +milestones have yet to be reached in order to achieve full commercialization potential.
 +In this talk, we will focus on the underlying physics, recent design and modelling
 +issues as well as on challenges in the growth, fabrication, and characterization of
 +the device. Recent realisations, including electrically tunable heterogeneous cascade
 +QCL and ambipolar dual-frequency QCL will be also discussed. Leeds experience
 +in joint work and day-to-day interaction between the design/modelling and growth/
 +fabrication/characterization teams will be shared with the auditorium.

 +**Seminar:** The Use of Multiplicity in Antenna and Propagation Engineering for Wireless Communication
 +
 +**Speaker: Prof Karu Esselle**
 +
 +**Abstract:** The use of multiple identical elements in a periodic or aperiodic fashion can solve challenges that cannot be solved using a single element. For decades, arrays of radiating elements have been employed to create narrow beams and frequency selective surfaces have been formed to filter electromagnetic waves propagating in free space. With the recent surge of research in Electromagnetic Band Gap (EBG), also known as Photonic Band Gap (PBG), the use of one- , two- or three-dimensional periodicity to achieve desirable radiation or propagation characteristics has received renewed interest. Multiplicity in one or several dimensions, with or without periodicity, has led to metamaterials with interesting properties. This presentation will focus on several selected practical applications of periodicity and multiplicity. They include EBG-resonator antennas (aka Fabry-Perot cavity antennas), leaky-wave antennas, band-reject filters, reconfigurable circuits, absorb or transmit frequency selective surfaces, dual-band artificial magnetic conductor surfaces, ultra-wideband planar proximity reflectors for bi-directional ultra-wideband antennas and frequency selective surfaces on energy-saving and float glass.

 +**Seminar:** The Cell Method for electrical engineering and Multiphysics problems
 +
 +**Speaker: Dr Fabio Freschi**
 +
 +**Abstract:** The seminar presents a numerical scheme for the solution of field problems governed by partial differential equations: the cell method. The technique lends itself naturally to the solution of multiphysics problems with several interacting phenomena. The Cell Method, based on a space-time tessellation, is related to the work of Tonti and to his ideas of classification diagrams or, as they are nowadays called, Tonti diagrams.
 +
 +After a brief outline of the theoretical basis of the method, some examples of multiphysics problems, which have been solved with the cell method, are described. Finally, the coupled nonlinear transient simulation of the induction heating for surface hardening process is analyzed in details.

 +**Seminar:** Maxwell-Plus-Plus: Clifford's Approach to Electromagnetism
 +
 +**Speaker: Dr Andrew Seagar**, Griffith University (Gold Coast)
 +
 +**Dates:** 10th May at The University of Queensland, St Lucia and 17th May at Griffith University, Nathan
 +
 +**Abstract:** Clifford, a student of Maxwell, set himself the task of developing an
 +algebra that somehow improved upon the tools of his time with the
 +objective of making it easier to solve Maxwell's electromagnetic
 +equations. Building on top of Grassmann's linear algebra, Descartes'
 +coordinate system, Cardano's complex numbers and Hamilton's
 +quaternions Clifford constructed a fundamentally new algebra. A
 +geometric algebra. This algebra was never adopted into mainstream
 +engineering for largely historical reasons. Clifford died from
 +tuberculosis at the relatively young age of 34 in 1879 and Maxwell
 +himself died at 48 later the same year. Contemporaries of Clifford
 +and Maxwell preferred to follow Gibbs's vector calculus approach as
 +popularised by Heaviside's rendition of Maxwell's equations in the
 +form we recognise today. They saw little reason to adopt Clifford's
 +new tool and disliked Maxwell's use of quaternions. Clifford and
 +Maxwell did not have the opportunity to tell their side of the story.
 +
 +This presentation first explores the connections between Clifford's
 +algebra and the other tools of the period: Grassmann's linear algebra,
 +Cardano's complex numbers, Hamilton's quaternions, Gibbs's vector
 +calculus, and simple geometric transformations. The method by which
 +Clifford's algebra is applied to electromagnetism is then examined and
 +the advantages which ensue from adopting that approach are
 +highlighted.

The aim of chipless RFID tag is to replace the existing barcodes used for item level tagging. Emerging new technologies are creating a paradigm shift in the chipless RFID application domain. New fabrication and material processing techniques have made it possible to create circuits and components that are nano-metre scale. Combined with fabrication techniques new materials are emerging that have the potential to challenge well known fundamental theories in physics.
 +A chipless RFID tag sensor provides identification data as well as monitors a number of physical parameters of tagged objects. The tag sensor is a passive microwave device that uses intelligent/ smart polymer materials for environment sensing. The tag sensor is designed by integrating the Microwave and Materials Engineering and realized through nanofabrication facilities.
 +The novelty of a Chipless RFID tag sensor has remarkable impact in research areas, economic and social aspects. To this date, a completely passive, printable, low cost, mass deployable, environmentally friendly Chipless RFID sensor node has not been reported for monitoring multiple sensing parameters. The RFID sensor measures temperature, pressure, humidity, pH level, presence of noxious gases and dielectric properties of media and objects. This wireless sensor tag is suited for applications such as, condition monitoring of perishable products and pharmaceuticals; wearable health monitoring tags for patients; structural health monitoring and numerous real world applications.

 +**Seminar:** Broadband Satellite Communications on-the-Move
 +
 +**Speaker: John Logan**, EM Solutions Pty Ltd
 +
 +**Abstract:** Satellite communications terminals are often used to achieve broadband data rates outside the traditional ISP environment. Increasingly there is a desire to use these terminals when fitted to a vehicle intended for urgent dispatch or to achieve on-the-move (OTM) satellite communications.
 +
 +EM Solutions has developed a Ka-band OTM terminal for use at military and commercial frequencies. At these frequencies, a pointing accuracy of < 0.3 degrees is required to maintain the satellite link over off road conditions. This is achieved by using closed-loop monopulse feed to track a satellite's telemetry signal or beacon, supplemented with data from the terminal’s gyroscopes.
 +
 +EM Solutions will outline the evolution of this OTM terminal from its beginnings on the Cairns Tilt Train to a recent export to Japan as part of their Disaster Recovery program, following the 2011 natural disasters in Fukushima.

 +**Seminar:** Smart Materials for Chipless RFID Sensors: Revolution in Identification and Sensing in the New Millennium
 +
 +**Speaker: A/Prof Nemai Karmakar**
 +
 +**Abstract:** In the era of information communication technology (ICT), RFID has been going through
 +tremendous development. RFID market surpassed $7.6 bn in 2012. RFID technology has the potential of replacing barcodes due to its large information carrying capacity, flexibility in operations and versatilities in applications. However, the penetration of RFID technology is hindered due to its high price tag. Many projects had been stalled only due to the cost of the tag. The application specific integrated circuits (ASICs) in RFID tags are the most expensive item. Fully printable chipless tags will provide competitive advantages over barcodes. If chipless RFID can be made less than a cent, the chipless RFID market will surpass $4 bn by 2019.
 +
 +With unique features of identification, tracing and tracking capabilities, RFID also gives value added services incorporating various sensors for real-time monitoring of assets, public installations and people from various backgrounds. Chipless RFID sensors for temperature, relative humidity, pH, impact and presence of noxious gas monitoring have opened new prospects. The market will grow to tens of billions. Since the chipless tag has no intelligence, the signal processing is done only in the reader. Therefore, a full
 +new set of requirements and challenges is needed to be incorporated and addressed, respectively, in the chipless RFID tag reader. This seminar addresses the development made in new smart materials for new chipless RFID tags and sensors, reader architecture and signal processing techniques at Monash University.

 +**Seminar:** An Optical Link for the Airborne Environment
 +
 +**Speaker: Conrad Fontes** (Micreo Ltd)
 +
 +**Abstract:** Optical links have been around for many years, but it has only been in the last decade or so that optical component specifications have reached a standard that has allowed an expansion into systems that operates in hostile environments. This presentation will take an in depth look at two optical links in production at Micreo Limited. The Airborne Optical Link (AOL), the first qualified airborne optical link in the industry, which presents many opportunities for outfitting future aircraft with photonic links. Secondly, the Microwave Optical Link (MOL10), a 40GHz bandwidth 19inch rack photonic link being trialled as an alternate to coaxial cable for routing multiple RF signals to different locations over short to medium distances. The presentation will also cover some of the challenges faced in manufacturing and qualifying a custom optical system for the hostile airborne environment, including packaging/routing fibre optics in a low volume chassis, understanding the interactions between RF and optical components in an optical link to achieve reasonable performance specifications such as Noise Figure and 1dB compression points, and achieving operation stability over wide temperature ranges and during vibration.

 +**Seminar:** Dielectric Resonator Antennas: From microwaves to optical frequencies
 +
 +**Speaker: Prof. Christophe Fumeaux**
 +
 +**Abstract:** Dielectric Resonator Antennas (DRAs) have been proposed in the 1980’s as alternatives to conventional low-gain printed-circuit antennas. They are typically composed of a low-loss dielectric block mounted on a ground plane. Their operation exploits the high “radiation losses” of open dielectric resonators operating in their low-order modes. DRAs are characterized by a small size, wide bandwidth, simple feeding and design versatility. Their most decisive advantage however may be their high radiation efficiency when realised with low-loss dielectric materials. This property is most relevant in the millimetre-wave frequency range, where conductor losses become significant in conventional printed antennas. The presentation will firstly review some of the DRA-related activities at the University of Adelaide, with examples of wideband geometries, advanced feeding methods, multi-mode multi-function designs and high-efficiency millimetre-wave devices. A second part of the talk will be dedicated to the extension of the DRA principle towards optical frequencies. The design and manufacture of a reflectarray of dielectric resonator nano-antennas operating at visible frequencies will be presented, with experimental validation as deflecting meta-surface for 633 nm wavelength light.

 +**Speaker:** Dr Andrew Seagar, Griffith University (Gold Coast)
 +
 +**Date:** 10 May 2013 15:00 at The University of Queensland, St Lucia and,
 +
 +**Date:** 17 May 2013 15:00 at Griffith University, Nathan
 +
 +**Abstract:** Clifford, a student of Maxwell, set himself the task of developing an
 +algebra that somehow improved upon the tools of his time with the
 +objective of making it easier to solve Maxwell's electromagnetic
 +equations. Building on top of Grassmann's linear algebra, Descartes'
 +coordinate system, Cardano's complex numbers and Hamilton's
 +quaternions Clifford constructed a fundamentally new algebra. A
 +geometric algebra. This algebra was never adopted into mainstream
 +engineering for largely historical reasons. Clifford died from
 +tuberculosis at the relatively young age of 34 in 1879 and Maxwell
 +himself died at 48 later the same year. Contemporaries of Clifford
 +and Maxwell preferred to follow Gibbs's vector calculus approach as
 +popularised by Heaviside's rendition of Maxwell's equations in the
 +form we recognise today. They saw little reason to adopt Clifford's
 +new tool and disliked Maxwell's use of quaternions. Clifford and
 +Maxwell did not have the opportunity to tell their side of the story.
 +
 +This presentation first explores the connections between Clifford's
 +algebra and the other tools of the period: Grassmann's linear algebra,
 +Cardano's complex numbers, Hamilton's quaternions, Gibbs's vector
 +calculus, and simple geometric transformations. The method by which
 +Clifford's algebra is applied to electromagnetism is then examined and
 +the advantages which ensue from adopting that approach are
 +highlighted.

 +**Seminar:** The Cell Method for electrical engineering and Multiphysics problems
 +
 +**Speaker:** Dr Fabio Freschi
 +
 +**Date:** 2 May 2013 13:00
 +
 +**Abstract:** The seminar presents a numerical scheme for the solution of field problems governed by partial differential equations: the cell method. The technique lends itself naturally to the solution of multiphysics problems with several interacting phenomena. The Cell Method, based on a space-time tessellation, is related to the work of Tonti and to his ideas of classification diagrams or, as they are nowadays called, Tonti diagrams.
 +
 +After a brief outline of the theoretical basis of the method, some examples of multiphysics problems, which have been solved with the cell method, are described. Finally, the coupled nonlinear transient simulation of the induction heating for surface hardening process is analyzed in details.

 +**Seminar:** The Use of Multiplicity in Antenna and Propagation Engineering for Wireless Communication
 +
 +**Speaker:** Prof Karu Esselle
 +
 +**Date:** 26 Apr 2013 10:00am
 +
 +**Abstract:** The use of multiple identical elements in a periodic or aperiodic fashion can solve challenges that cannot be solved using a single element. For decades, arrays of radiating elements have been employed to create narrow beams and frequency selective surfaces have been formed to filter electromagnetic waves propagating in free space. With the recent surge of research in Electromagnetic Band Gap (EBG), also known as Photonic Band Gap (PBG), the use of one- , two- or three-dimensional periodicity to achieve desirable radiation or propagation characteristics has received renewed interest. Multiplicity in one or several dimensions, with or without periodicity, has led to metamaterials with interesting properties. This presentation will focus on several selected practical applications of periodicity and multiplicity. They include EBG-resonator antennas (aka Fabry-Perot cavity antennas), leaky-wave antennas, band-reject filters, reconfigurable circuits, absorb or transmit frequency selective surfaces, dual-band artificial magnetic conductor surfaces, ultra-wideband planar proximity reflectors for bi-directional ultra-wideband antennas and frequency selective surfaces on energy-saving and float glass.

 +**Seminar:** Terahertz quantum cascade lasers: physics and challenges in design, growth and fabrication
 +
 +**Speaker:** A/Prof Dragan Indjin
 +
 +**Date:** 9 Apr 2013 1:00pm
 +
 +**Abstract:** Terahertz quantum-cascade lasers (THz QCLs), first realised in 2002, have now
 +reached technological maturity. However, with maximum operating temperatures
 +around 200K in pulsed mode, and ~ 250K in the strong magnetic field, a number of
 +milestones have yet to be reached in order to achieve full commercialization potential.
 +In this talk, we will focus on the underlying physics, recent design and modelling
 +issues as well as on challenges in the growth, fabrication, and characterization of
 +the device. Recent realisations, including electrically tunable heterogeneous cascade
 +QCL and ambipolar dual-frequency QCL will be also discussed. Leeds experience
 +in joint work and day-to-day interaction between the design/modelling and growth/
 +fabrication/characterization teams will be shared with the auditorium.

 +**Seminar:** Chipless RFID: Revolution in Identification in the New Millennium
 +
 +**Speaker:** A/Prof Nemai Karmakar
 +
 +**Date:** 17 Jan 2013 1:00pm
 +
 +**Abstract:** Radio Frequency IDentifcation (RFID) is one of the fastest growing technologies in recent decades. RFID is an omnipotent identification technology that has many significant applications. As for an example, car immobilizers use RFID technology. However, the penetration of RFID in low cost item level tagging is hindered due to its high cost. The application specific integrated circuit (ASIC) micro-chip in the RFID tag is the most expensive item in a tag. Researchers have been working to remove the chip from the tag so that the tag can be made fully printable and low-cost. However, printing microwave circuits on low grade packaging and labelling materials is not a trivial task. Tremendous design flexibility and high precision printing with high conductivity ink are needed to design microwave circuits on these materials. Additionally to these stringent requirements, reading of this tag is tremendous challenging due to its low fidelity response. No conventional protocols can be added in the chipless RFID tag as they have no on-board signal processing capability. Therefore, a fully new development of chipless RFID reader is needed. This seminar will present chipless RFID tag and reader for low cost item level tagging.
